Abstract

Provided is a method for sorting resources, an electronic device and a storage medium, relating to the field of artificial intelligence technology, and specifically to the fields of intelligent search, information flow, intelligent question and answer, and other technologies. The method includes: determining a state feature of a target object; matching the state feature with a plurality of candidate state categories of the target object to obtain a matched candidate state category as a target state category; and adjusting a resource order in a candidate resource set of the target object based on a target resource feature of the target object associated with the target state category.

First claim

What is claimed is:

1 . A method for sorting resources, comprising:
determining a state feature of a target object; matching the state feature with a plurality of candidate state categories of the target object to obtain a matched candidate state category as a target state category; and adjusting a resource order in a candidate resource set of the target object based on a target resource feature of the target object associated with the target state category.

2 . The method of claim 1 , further comprising: determining the plurality of candidate state categories of the target object by:
obtaining a plurality of pieces of historical state description information of the target object, wherein the historical state description information comprises a first object feature of the target object and a first environment feature associated with the first object feature; performing a data dimension reduction operation on the plurality of pieces of historical state description information to obtain a plurality of historical dimension reduction features; and performing cluster analysis on the plurality of historical dimension reduction features to obtain the plurality of candidate state categories of the target object.

3 . The method of claim 1 , further comprising: determining the target resource feature of the target object associated with the target state category by:
obtaining historical operation resources of the target object under the target state category within a preset time period; and determining the target resource feature associated with the target state category based on the historical operation resources, wherein the target resource feature comprises a positive feedback resource feature and/or a negative feedback resource feature; wherein the positive feedback resource feature is used to characterize a feature of a resource that the target object is interested in; and the negative feedback resource feature is used to characterize a feature of a resource that the target object is not interested in.

4 . The method of claim 3 , wherein determining the target resource feature comprising the positive feedback resource feature comprises:
extracting a plurality of first sub-resource features that the target object is interested in from a plurality of positive feedback resources in the historical operation resources; wherein the positive feedback resources are resources that the target object is interested in; and fusing the plurality of first sub-resource features to obtain the positive feedback resource feature.

5 . The method of claim 4 , wherein extracting the plurality of first sub-resource features comprises:
constructing a first resource graph based on the plurality of positive feedback resources, wherein the positive feedback resources are used as nodes in the first resource graph, and access time sequences between the positive feedback resources are used as connection edges between the nodes; extracting a plurality of first resource sequences from the first resource graph using a random walk strategy; and performing text encoding on first text descriptions of the plurality of first resource sequences to obtain the plurality of first sub-resource features; wherein the first text descriptions of the first resource sequences are constructed based on text information of resources in the first resource sequences.

6 . The method of claim 3 , wherein determining the target resource feature comprising the negative feedback resource feature comprises:
extracting a plurality of second sub-resource features that the target object is not interested in from a plurality of negative feedback resources in the historical operation resources; wherein the negative feedback resources are resources that the target object is not interested in; and fusing the plurality of second sub-resource features to obtain the negative feedback resource feature.

7 . The method of claim 6 , wherein extracting the plurality of second sub-resource features comprises:
constructing a second resource graph based on the plurality of negative feedback resources, wherein the negative feedback resources are used as nodes in the second resource graph, and access time sequences between the negative feedback resources are used as connection edges between the nodes; extracting a plurality of second resource sequences from the second resource graph using a random walk strategy; and performing text encoding on second text descriptions of the plurality of second resource sequences to obtain the plurality of second sub-resource features; wherein the second text descriptions of the second resource sequences are constructed based on text information of resources in the second resource sequences.

8 . The method of claim 1 , wherein adjusting the resource order in the candidate resource set comprises:
determining a candidate resource feature of a candidate resource in the candidate resource set; determining resource similarity between the candidate resource feature and the target resource feature; and adjusting a recommended order of the candidate resource in the candidate resource set based on the resource similarity, wherein the greater the resource similarity, the greater the adjustment of the recommended order of the candidate resource in the candidate resource set.

9 . The method of claim 8 , wherein the greater similarity between the candidate resource feature of the candidate resource and a positive feedback resource feature in the target resource feature, the greater improvement of the recommended order of the candidate resource; and
the greater similarity between the candidate resource feature of the candidate resource and a negative feedback resource feature in the target resource feature, the greater reduction of the recommended order of the candidate resource.

10 . The method of claim 1 , wherein determining the state feature of the target object comprises:
obtaining a second environment feature and a second object feature of the target object; and performing a data dimension reduction operation on the second environment feature and the second object feature of the target object to obtain the state feature of the target object.

11 . An electronic device, comprising:
at least one processor; and a memory connected in communication with the at least one processor; wherein the memory stores an instruction executable by the at least one processor, and the instruction, when executed by the at least one processor, enables the at least one processor to execute:
determining a state feature of a target object;
matching the state feature with a plurality of candidate state categories of the target object to obtain a matched candidate state category as a target state category; and
adjusting a resource order in a candidate resource set of the target object based on a target resource feature of the target object associated with the target state category.

12 . The electronic device of claim 11 , wherein the instruction, when executed by the at least one processor, enables the at least one processor to further execute:
determining the plurality of candidate state categories of the target object by:
obtaining a plurality of pieces of historical state description information of the target object, wherein the historical state description information comprises a first object feature of the target object and a first environment feature associated with the first object feature;
performing a data dimension reduction operation on the plurality of pieces of historical state description information to obtain a plurality of historical dimension reduction features; and
